Site details
Site description: The site is located south-east of Studjenoe Karasukskiy rayon of Novosibirsk region. The hole represents a vast system of fresh and bracken lakes alternating with major water-meadows, steppe and saline areas. Bird counts were performed in June-August of 2007-2009 and partially in August of 2010. When investigating the wetlands, there was realized the absolute account of the majority of birds without extrapolation to the territory. The information of the number of birds in 1990-2000 during autumn flight was received from the inspector Gusev of the preserve “Yuzhnay”. Our own observations allow to consider this data reliable. The further investigations are required as the nesting of the whole number of rare species is possible in this region. Also the investigation of the whole IBA territory is needed, as the achievement of the threshold values of the criterion A4.1 is quite possible here for some birds (Phalacrocorax carbo, Ardea cinerea etc.).
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that meets the thresholds for at least one criterion described in the Global Standard for the Identification of KBAs.
Additional biodiversity: The following semi-aquatic birds were noticed on nesting and movements in June-August: Black-necked Grebe, Red-necked Grebe, Great Bittern, Great Egret, Whooper Swan, Mute Swan, Mallard, Gadwall, Garganey, Eurasian Wigeon, Common Teal, Northern Shoveler, Northern Pintail, Common Pochard, Tufted Duck, Red-crested Pochard, Common Shelduck, Common Coot, Little Ringed Plover, Red-necked Phalarope, Northern Lapwing, Redshank, Marsh Sandpi-per, Wood Sandpiper, Little Stint, Temminck’s Stint, Curlew Sandpiper, Dunlin, Ruff, Curlew, Black-tailed Godwit, Black-winged Stilt, Pied Avocet, Common Snipe, White-winged Tern, Black Tern, Little Tern, Caspian Tern, Com-mon Tern, Larus barabensis, Mew Gull, Pallas's Gull, Black-headed Gull, Little Gull, Bearded Parrotbill etc. Non-bird biodiversity: The majority of wetlands are rich in fish (Crucian Carp, Perch, Wild Common Carp etc.)
Delineation rationale: 2014-08-12 (BL Secretariat): centroid coords adjusted to 53°32'35'N 77°36'39'E and site area changed to (or confirmed as) 25470 ha (rounded), on basis of refined polygon downloaded from Spatial Database on Important Bird Areas of Russia 2014 (© Russian Bird Conservation Union, © Transparent World).
